    gcc: Fix specs generation for ARC
    
    GCC's built-in spec for LD is missing a space after
    "--eh-frame-hdr" thus with the next option merged together they
    are not understood by LD and so LD fails.
    
    Back-port from upstream GCC, see:

+Subject: [PATCH] [ARC] Update LINK_EH_SPEC linker spec.
+
+With no trailing space in LINK_EH_SPEC linker spec gets generated as:
+------------------------>8---------------------
+%{!r:--build-id} --eh-frame-hdr%{h*} ...
+------------------------>8---------------------
+
+or even worse if hash style is added:
+------------------------>8---------------------
+%{!r:--build-id} --eh-frame-hdr--hash-style=sysv %{h*} ...
+------------------------>8---------------------
+
+Now if that spec is really used by LD then it fails inevitably
+saying that it doesn't know option "--eh-frame-hdr--hash-style=sysv".
